Chmerkovskiy previously left "Dancing With the Stars" after Season 15 and came back for Season 18, which he won with partner Meryl Davis, Us Weekly reported.

"When I came back to the show, it was not the same," Chemerkovskiy said. "I was different, probably. ... When I came back, I saw this amazing talent, Val [Chmerkovskiy, his brother] included ... I looked at it and thought they can do much more and better; I was taking up a huge spot."

In a later interview on "Watch What Happens Live," Chmerkovskiy expressed his love for the show but restated that it has become different from what he knew.

"I saw that there were a lot of changes last season," he said according to E! News. "I took a year off. I skipped two seasons, and I came back. I personally fell in love with the show. It's not something I need to say now that I'm not even part of it, but it's definitely amazing entertainment. ... I do think it needs to stay on."

The dancer also revealed his true issue with the long-running dancing competition show.

"I'm a big supporter of anything dance related, and I think it's brilliant," Chmerkovskiy said. "My problem is that we're running out of legitimate celebrities. That's the problem."

Earlier this month, Rob Wade, Season 19 showrunner, said he wants Chmerkovskiy to be part of the upcoming season.

"I don't know whether it's going to be as a dancer," he told E! News. "I think there's a number of different things we can talk to him about and the way he'd be involved in the show.
